Performance Tuning Apache and Passenger

In this video I go into depth on tuning a real apache/passenger setup using httperf, htop, iftop and a handful of other tools.

I recorded this video almost a year ago. I was delaying its release because I wanted to do a little more editing, addition of some graphs, bumpers, etc. but I decided its more important to release it than actually sit on it for something I'll never have the time to do.
